To a/ZZ whom it may concern:

Beit known that we, STUART JAcxsoN WELTER and G RovER CLEVELAND WELTER,

and residents o f Roswell, in the' county of Chaves. and Territory of New' Mexico, have invented a new and Improved Lubricator, of which the foltion.

Our invention relatesto a device for ubricating wagon-axles successfully and doin of 'taking the whee from the axle when the oil is applied.

On account ofthe inconvenienceof taking wheels from axles it is well known that they are frequently left on so longV asto become d vand to burn out thebearings..

t is the principal obj ect lof our invention to provide an oiling device which will be efficient, sim le, can be ii ed with axle.

oil while a wheel is on the 'Reference-is to be had to the accompanying drawings, forming a part of this specifi- `catlon, 1n which' similar characters ofrefer-l ence indicate corresponding parts in all the es. *.-Figure 1 is a side elevation, partly in section, on theline 111 of Fig. 2, of a cast axleskein, `showing the rinciple of Vour invention. Fig'. 2 is a sectiona -view of thesame on the line 2 2 of Fig. 1. .'Fig. 3 isa sectional view similar to Fig. 2, showing a way of applying the-invention to a steel skein.` Fig. 4 is a side elevation of the device shown in Fig. 3. Figs. 5 and 6 are sectional-views on the lines l5 v5 and .6 6,' respectively, and Fig. 7 is a perspective view of the oiling attachment shown 1n Fig. 1.

Referringvfrst to Figs. 1, 2, 5, and 7, the axle-skein a is constructed of cast metal, its

manner. v.Its bearing-surface a. .is provided, ression a3 extends to a receptacle which is preferably cast in one piece with the skein. This recepltacle is provided with a passage b',

the letter c.) The oiler has a s iding tube d upon its outer surface, and this tube is provided with a slot d', which receives a lug c u on the body of the oiler. At the rear of t e'slot d is a shoulder d, hichis `adapted lto come-into contact with the lug, so as to and inexpensive, and yet which ing it.

revent the removal ofthe tube from the ody of the oiler. A iston e is mountedin the end ofthe oiler, eing normally urged forward by a spring-)Sand the oiler is provided with lugs c2 forpreventing the removail lof the piston from it. The piston is provide with avplunger e', projecting outwardly and bearing against a shouldervba. The oiler is rovided withv a pin adapted to enteran' L- shaped slot b2 in the barrel b forholding the oiler in position. The oiler is provided with Vscrew-threads c3,v by means of -can be attached to it, this cap being prowhich a cap h vided with a ring h for convenience in operating it,y y

The operation of the device is very simple. In order to lill it with grease,'the tube d is drawn out to the position indicated in dotted lines inFig. 7 s andl the grease placedinthrough the slotd The oiler is then cylindrical passage b', the pin q being moved t ough the slot b2 and turned so that it will ,be retainedv in position. The spring f will force the pin 'back into the reversely-extending portion of the slot, and thus assist inhold- This operation will force the grease into the assage a3 i faces of t e wheel.- 's The turning of the-wheel will distribute the grease, and when-it is `desired to lubricate the bearing again it will be necessary merely to withdraw: the oiler, fill it, and replace it, as before. The wheel does not have to be removed. If it is desired to usewoil yinstead of grease, the device can be placed with'i'tsend entering the passage b and the oil poured in through the lot d', as before. l The o il then enters the tu e, and if any is spilled it goes into the passage b and the forcing of the oiler to its proper position forces the oil to. the bearing-surfaces.

In the formv shown in Figs. 3, 4, and 6 a steel skein A is shown, this being provided with adepression a and passage as, as escribed above. A collar 7c is secured tothe skein, and this holds a plate Z, which is' provided with a receptacle m. The plate lis also (preferably riveted tothe skein, as indicate The receptacle mis provided wit-hfaJ passage m', communicating witlithe cnet-joint B, joint b?. The p ate is also provided with an extension n, passing into the depression a.

and extending of said depression.

claim as new` and desire to secureby Letters Patent- 1. In a lubricator for wagon-axles, the combination with a skein having a passage, of a receptacle having a passage communicating with the irst-mentioned-passage, and a member adapted to enter said second. passage for holding a lubricant therein; said recepta'clel having means for holding said memberm the passage, and said member having means for preventing the disengagement of said first-mentioned .means 2, In a lubricator for wagonaxles, the combination with -.a skein having a bearingsurface provided with a depression and a passage communicating with said depression, of a receptacle having a passage communicating with said first-mentioned passage, and a member adapted to enter said second passage for holding a lubricant therein; said receptacle having means for holding said member in the passage, and said member having resilient means for preventing the disengagement of'sid first-mentioned means.

3. In a lubricating device, the combination with a bearing element having a depression upon a bearing-surface thereof, and a passage communicating with said depression, of a receptacle mounted adjacent to said bearing element and provided with a passage .communicating with the irst-mentioned passage and with a shoulder near its inner end, and a member mounted within said second passage, said member being provided with a plunger adapted to engage said shoulder, and with a spring for forcing said lun- -ger against the shoulder, said receptac e being provided with means for locking the member in position.

4. A lubricating device comprising a re- 'I ceptacle having a passage for communicatingwith abearing and providedwith a shoulder at its inner end and a bayonet-slot at its outer end and an oiler in the receptacle and provided with a spring-pressed plun er engaging the shoulder 'of the receptac e and with a pin engaging the bayonet-slot of said receptacle.
